Good ideea with the bed risers, im from Europe so Walmart is oit of reach but my furniture have some good space under the TV, i need to make some more measurements maybe i can fit the 505C. Is it a big problem if the reflex port will be exactly at the back of the furniture? No much room for the reflex port, maybe if i cut some of the furniture exactly where the port will sit. Excuse my English, its not my native language!
